If you don't care for Spotify's current automatic sharing of what you're listening to in your Facebook feed, the new "private listening" feature may make you happy. According to Business Insider, when the update rolls out, you'll see a toggle to turn the broadcasting on or off easily.

You can also go to your Spotify Preferences and uncheck the box to not share music with Facebook (or disconnect from Facebook entirely), but the toggle is much more user-friendly. The "private listening" mode will also be available from the File menu. See Spotify's blog post for more on your sharing options.
